JSON-RPCでAjax - 準備編

JSONIC いろいろ試してみました。すっごい便利。ガンガン Ajax するなら Teeda や SAStruts を使わずに Seasar2 と JSONIC だけで十分そう。

そんな訳で Seasar2 、 JSONIC 、 ExtJS で Ajax アプリを作っていくチュートリアルを書いてみる。まずは準備編。

S2 セットアップ

http://s2container.seasar.org/2.4/ja/setup.html を参考に Eclipse で Tomcat プロジェクトを作成し S2 環境を整える。今回は S2 だけを利用するので Dolteng を使わない場合にしたがった。プロジェクト名は「jsonic」。あと dicon ファイルは下記のような感じで。

■app.dicon

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE components PUBLIC "-//SEASAR//DTD S2Container 2.4//EN"
	"http://www.seasar.org/dtd/components24.dtd">

</components>

■convention.dicon

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE components PUBLIC "-//SEASAR//DTD S2Container 2.4//EN"

	</component>
	<component class="org.seasar.framework.convention.impl.PersistenceConventionImpl"/>
</components>

■creator.dicon

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE components PUBLIC "-//SEASAR//DTD S2Container 2.4//EN"

</components>

■customizer.dicon

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE components PUBLIC "-//SEASAR//DTD S2Container 2.4//EN" 
	"http://www.seasar.org/dtd/components24.dtd">
<components>

■s2container.dicon

    <include condition="#ENV == 'ct'" path="hotdeploy.dicon"/>
    <include condition="#ENV != 'ut' and #ENV != 'ct'" path="cooldeploy.dicon"/>
</components>

JSONIC セットアップ

http://jsonic.sourceforge.jp/ から最新の JSONIC をダウンロードし jar ファイルをプロジェクトの WEB-INF/lib へ配置、 Eclipse のビルドパスを通す。次に web.xml を作成。内容は下記の通り。

■web.xml

以上で S2 Hot deploy のサクサク環境で JSONIC が利用できるようになりました。
